I'm about to order magnaflow 40's from Autoanything.com which inlet/outlet size do I need? What's best delta flow or super 40. Which outlet do I need center, offset or dual? Thanks for the help, GJTcodered

Offset Inlet/Center Outlet

"Style"/"Model" of the 40 Series is to sound preference...

Original "40s" are the most aggressive

"Delta Flow" "40s" is a little less aggressive

"Super 40s" are deeper and aggressive like the "40 Series"

If you're just hookin' up to an otherwise stock exhaust system...do the 2 1/4...

Due to the "open-chamber" design of the Flowmasters...it's not as important on the inlet/outlet size like it is with the Magnaflows. But 2 1/4" should be doing whomever is doing the install a favor.

Do I get just one muffler with dual outlet or do I need two. I know, I know nothing.

You need 2 mufflers to replace the 2 you have on right now

Aloha,

just my opinon, go with the super 40's you will not regret it... Got them on my MM with a bassani X-pipe, delete tips and soon to be installed Kook's headers. If not you will in the end :coolman:

I have the Flowmaster Super 40's on a complete stock exhaust system. I think they sound great, deep, and aggressive saying "Back off." In my mind, I think this would be your best choice.
